#
# DESCRIPTION:
# Verify 'zpool trim -r <rate>' rate limiting.
#
# STRATEGY:
# 1. Create a pool on a single disk.
# 2. Manually TRIM the pool with rate limiting.
# 3. Verify the TRIM can be suspended.
# 4. Restart the TRIM and verify the rate is preserved.
#
# NOTE: The tolerances and delays used in the test below are intentionally
# set be to fairly large since we are capping the maximum trim rate. The
# actual trim rate can be lower. The critical thing is that the trim rate
# is limited, the rate is preserved when resuming, and it can be changed.
